Also, I've been having thoughts about applying aftercare practices to kink games with heavy themes; I'm not sure how to approach it, though. My current idea is having a separate, optional scene that can be opened up whenever / is prompted at times, that features a generalised 'aftercare' story, just to ease players out of things if they need it

Obviously that's putting a lot of faith in the ability of kink games to be immersive, but I'm sure it couldn't hurt
